WILLIAM KANE, OF PHILADELPHIA, PEN 'NSYLVANIA.

AUTOMATIC GAS-REGULATOR.

Specification of fitters Patent.

Patented Dec. '7, 1920.

Application filed November 19, 1919. Serial No. 339,160.

To all whom it may concern:

Be it known that 1, WILLIAM KANE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Gas-Regulators, of which the following is a specification.

One object of my invention is to provide an improved device which automatically operates to vary the supply of gas fuel to a burner so that the burner will supply a desired amount of fuel to suit various requirements. For example my invention can be used advantageously in connection with a steam generating apparatus for vulcanizing or other purposes where it is necessary to maintain a uniform pressure of steam and when so used will automatically operate through the medium of the steam generated to regulate the amount of gas fuel to keep the steam at a desired uniform pressure.

Another object is to so construct my invention that it can be used without material change for connection to apparatus of various sizes since gas pipes of different diameters can be easily attached thereto and it will operate in connection with large apparatus as well as in connection with small apparatus.

Another object is to make the parts of my invention in such manner that they can be easily made, put together, and taken apart.

A further object is to make my invention of a simple construction and so that it can be easily regulated to suit numerous requirements.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in p which Figure 1 is a central vertical sectional elevation of my improved regulator, and

Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

Referring to the drawing, 3 represents a hollow base section closed at its bottom and sides and open at its top. This section is preferably made comparatively large and substantially square in cross section, one of the sides 4 is preferably thickened and as illustratedthis thickening of the side is produced by providing a boss 5 which extends substantially throughout the height and width of the section to permit tapped openings, such as the opening 6 to be provided hree pins 14 have their upper ends screw threaded, as shown at 15, and are adapted to be screwed into tapped holes in the partition 12. The portions 16 of the pins 14 between the heads 17 v and the screw threaded parts 15 are made smooth and extend throu h holes in a disk valve 18; said disk valve eing of larger diameter than the aperture 13. The heads'17 of the pins 14 are larger than the holes in the disk valve 18 and serve to normally support the disk valve in a position away from the partition 12, as shown in Fig. 1. However, it will be noted that the disk valve is free to slide upwardly on the pins 14 as guides and if raised from the position shown in Fig. 1 would tend to vary the amount of gas passing from the chamber 7 into the chamber 19 provided by the top section 9.

A tube 20 has a screw threaded nipple extension 21 which fits within the bottom 22 of the base section 3 and extends below said bottom 22. This nipple extension permits the attachment of a steam pipe (not illustrated) which, for example, may lead from a steam boiler or generator for the purpose of supplying steam to a vulcanizing apparatus or other apparatus to which it is desired to supply steam at a uniform pressure.

A lever 23 has one end pivotally connected at 24 to a plug 25 which may be screwed into the side of the base section and this lever normally extends over the top of an arcuate portion 25 of the tube 20. A free end 26 of the lever 23 is positioned directly below the middle of the disk valve 18.

The side 27 of thetop section 9 is thickened in a manner similar to the side,4 of the bottom or base section 3 by providing a boss 28; said boss being of comparatively such as 29 to be formed therein for the attachment of an outlet gas pipe 29 which may lead to a burner or burners of the steam boiler or generator above mentioned. It will be noted that by providing the comparatively large boss 28 that outlet gas pipes of various diameters can be readily attached thereto. An adjusting rod 30 has a screw threaded portion 31 which fits within a tapped hole 32 in the extreme top of the sec tion '9 and has a stem 33 which depends through the aperture 13, as clearly shown in Fig. 1. The upper end of this adjusting rod is provided with a knob 34 whereby it can be turned to vary the position of the bottom end of the stem 33 relatively to the bottom of the partition 12.

The adjusting rod 30 canbe moved so as to extend various distances below the plane of the bottom of the partition 12 and when thus positioned, the disk valve 18 can only be raised until it strikes the bottom of said adjusting rod 30. By this means, as will hereinafter be described, the device can be made to operate so that the disk valve can be limited in its upward or closing movement to suit various requirements.

In the voperation of my device, considering that the pipe 29 is supplying gas to a burner for generating steam and that a portion of said steam is conveyed to said tube 20 by means of a .pipe (notillustrated) which is connected to the nipple extension 21,'when the steam attempts to increase beyond a certainpredetermined pressure,.the free arcuate end portion 25 of the tube 20 will tend to straightenout and in so doing will engage the lever 23 between the pivot 24 and the end. 26 and move said end 26 into engagement with the disk valve 18 and thereby raise the disk valve on the pins 14 as guides toward the aperture 13. This will out off a portion of the gas supply passing through the aperture 18 and consequently reduce the amount of gas passing to the burner through the pipe 29. The flame of the burner will then be reduced and the pressure of the steam will consequently be reduced. Vhen the steam is thus reduced in pressure, the arcuate portion 25 of the tube 20 will again move toward its normal arcuate position to permit the lever 23 to lower and the disk valve 18 will consequently drop to permit moregasto be supplied to the pipev29. In this manner the steam is kept at a uniform pressure. By havingthe lower end of the adjustingarod 30 extending below the plane of the-bottom of the partition 12, it is impossible for the disk valve 18 :to entirely close the aperture 13 so that the burner will never beientirely extinguished. Thus it is unnecessary to provide any additional bypasses from the gas .to the burner since the amounteof constant supply can be varied by adjnstingthe Verticalposition of therod 80. mbltfiit fi fizmql miq 'ill l d sil dWilhbe511p- 20 by swinging the lever 23 upwardly and then unscrewing the tube 20, after which the entire lever and plug 29 can be removed. It will he further understood that by interposing the lever 23, a mechanical advantage is attained since a very small movement of arcuate portion 25 of the tube 20 will im part a comparatively great movement to the end 26 of the lever 23.

The parts of my invention can be easily assembled and the pins 14 provide smooth guides and prevent the disk valve 18 from jamming or becoming distorted in any manner. V

lVhile I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims. 7
